+# systemd-zfs-partition-backup.sh
+
+## How to:
+
+1. rsync is required and used internally with `--delete` to get rid of already deleted files (with zfs we have snapshots)
+2. systemd-automount should be working for the device to back up (=fstab)
+3. A zfs dataset will be searched with the name of the partition. If it is there it will be used for the backup.
+4. if the partion is encrypted an entry in the `crypttab` will automatically be found by automount.
+5. have fun.
+
+
+### crypttab
+
+```
+# /etc/crypttab example
+
+SomeDisk_SDSSDH0000G_123456789-part2           /dev/disk/by-id/SomeDisk_SDSSDH0000G_123456789-part2               /etc/.crypt/SomeDisk_SDSSDH0000G_123456789-part2.key       noauto,x-systemd.device-timeout=5s
+```
+
+### fstab
+
+```
+# /etc/fstab example
+
+# Note that the connector name has been removed from the mountpoint.
+# The automount unit will be named after that and so must the zfs dataset

+# The following name takes the name we gave our disk in the crypttab (first column).
